I played about 1 hour 30 minutes of this of the first three classes. I had a very frustrating bug with Thief where the thing that gave both you and the enemy Counter X, would repeatedly and seemingly randomly trigger even when there was no way it could, like if I put 1 into a split-dice-in-two and it was Counter 5, I could get locked dice even though it should've been two 1's.
Next I was playing Robot and crashed when, I think the enemy that gives random crystal weapons, got one saying "Gain a random blessing" and it crashed just before the AI was seemingly about to play it.
First episodes for each character could be more interesting I think, seems like they were just bonus round modifiers + new items, without much added difficulty. I wanted to play the 2nd-6th episodes of each character but was locked from that.
